Results of the concerted action on power conditioning and control

The Concerted Actions have been established to identify possibilities for improvement and optimization of photovoltaic (PV) systems. Some of the achievements of the Power Conditioning and Control section are presented here. The items selected are of general interest because of their applicability to every PV system. They describe the influence of power conditioning structures on energetical system performance and include: (Detailed) Performance of power conditioning units as a function of: -Power efficiency, loss parameters, self-consumption and no-load-behaviour, -Insolation characteristics at different sites, -Different load power distributions, -Inverter sizing, -Seasonal fluctuations; (Briefly) PV generator performance as a function of: -Insolation characteristics at different sites, -Thermal operating conditions, -Orientation, -Voltage adaption; Conclusion and recommendations.
